Abstrakt: Calcium (Ca2+) ions are critically important in orchestrating countless regulatory processes in eukaryotic cells. Consequently, cells tightly control cytoplasmic Ca2+concentrations using a complex array of Ca2+-selective ion channels, transporters, and signaling effectors. Ca2+transport across various cellular membranes is highly dependent on the intrinsic properties of specific membrane compartments and conversely, local Ca2+changes have profound effects on the membrane lipid composition of such membrane sub-domains. In particular, inositol phospholipids are a minor class of phospholipids that play pivotal roles in the control of Ca2+-dependent signaling pathways. In this review, we will highlight some of the recent advances in this field as well as their impact in defining future research directions.
